Wolfman, very sorry you're going through this, wow. Remove every important document from the house and any items of value until she's gone. Talk to a lawyer about your legal options for getting her out. It varies from state to state, here in TX if someone is allowed to live in your house for a certain length of time and receives mail there then they are a resident and you can't just kick them out, you have to go through eviction proceedings. If she hasn't been there long then you may be able to ask her to leave, and if she refuses then you can call the police for assistance. But I don't know the specifics and that's why I suggest talking to a lawyer first.
